NgoDisemba ka-2019, kwaqhambuka usulelo lwe-SARS-CoV-2 (isifo esiqatha sokuphefumla i-coronavirus 2) savela eWuhan, kwiphondo laseHubei, eTshayina, kwaye sasasazeka ngokukhawuleza kwihlabathi liphela, emva kokubhengezwa njengobhubhani yi-WHO nge-11 kaMatshi ka-2020. Ngo-Oktobha 14, 2020 ehlabathini lonke kuye kwabikwa amatyala angaphezu kwezigidi ezingama-37.8, nto leyo ebangele ukufa kwabantu abayi-1,081,868 .I-coronavirus entsha ka-2019 (2019-nCoV) isasazeka ngokulula phakathi kwabantu ngesizukulwana se-aerosol ukusuka kubantu abosulelekileyo bekhohlela, ukuthetha okanye ukuthimla xa besondelelene nabanye, kwaye inexesha lokufukamela eliqala kwi-1 ukuya kwi-14 yeentsuku.[1]
Ulandelelwano lwemfuzo olwenziwe ngo-2019-nCoV, nge-7 kaJanuwari, 2020, luvumele uphuhliso olukhawulezileyo lwesixhobo sovavanyo lokuxilonga nge-RT-PCR (reverse transcription polymerase chain reaction).Ngaphandle kokuthintela usulelo, ukufunyaniswa kwalo kwangethuba nangokukhawuleza kubalulekile ekulawuleni ukusasazeka kwale ntsholongwane .Iiswabs zeNasopharyngeal (NPS)zisetyenziswa kakhulu kwaye zicetyiswa njengesampulu eqhelekileyo yokuxilongwa kwentsholongwane yokuphefumla, kubandakanya i-SARS-CoV-2.Nangona kunjalo, le ndlela ifuna uqhagamshelwano olusondeleyo kunye neengcali zempilo, ukonyusa umngcipheko wokosuleleka kwaye kunokubangela ukungakhululeki, ukukhohlela kunye nokopha kwizigulana, kunganqweneleki kangako ekujongweni komthamo wentsholongwane egazini.
Amatheukusetyenziswa uxilongo losulelo yintsholongwane uvelise umdla kwiminyaka yakutshanje, ikakhulu ngenxa yokuba bubuchule non-invasive, kulula ukuqokelela kwaye inexabiso eliphantsi.Ngenxa yokungabikho kweprotocol esemgangathweni, ukuqokelelwa kwamathe kunokufumaneka: a) amathe avuselelwe okanye angavuselelwayo t okanye nge-swabs yomlomo.Usulelo oluninzi lwentsholongwane lunokubonwa kumathe, njengentsholongwane ye-Epstein Barr, i-HIV, intsholongwane ye-Hepatitis C, i-Rabies virus, i-Human papillomavirus, i-Herpes simplex virus kunye ne-Norovirus.Ukongeza, i-saliva iye yaxelwa njengendlela efanelekileyo yokufumanisa i-coronavirus nucleic acid ehambelana ne-syndrome enzima yokuphefumla kwaye, kutshanje, i-SARS-CoV-2.
Iinzuzo zeusebenzisa iisampulu zamathe kuxilongo lwe-SARS-CoV-2, njengokuziqokelela kunye nokuqokelela ngaphandle kwezibhedlele ngaphandle kwezibhedlele, kukuba iisampulu ezininzi zinokufumaneka ngokulula kwaye kukho isidingo esincitshisiweyo sokuphathwa kweengcali zempilo ngexesha lokuqokelela isampula, ukunciphisa umngcipheko wokudluliselwa kwe-nosocomial, ukunciphisa ixesha lokulinda uvavanyo, kunye nokunciphisa i-PPE, ukuthutha. kunye neendleko zokugcina.Olunye uncedo lwale ndlela yokuqokelelwa ingangeneleli kunye neyoqoqosho yimbono engcono njengokujongwa koluntu, kokubini kusulelo olungenazimpawu kunye nokukhokela ukuphela kokuvalelwa.
